IAG sacks otherwise good employee that didn't hit keystrokes per hour quota & Fair Work is cool with it

IAG, Australia's largest insurance company (NRMA/CGU/SGIO & more), sacked an otherwise excellent employee with 18 years of service after installing a keylogger on their work supplied computer and finding "a number of hours where zero keystrokes were recorded on the employee's device; up to 85% of work hours in one month". The worker took it to the Fair Work Commission who unfortunately agreed with IAG's decision, saying that the former employee offered no "credible [alternative] explanation" for the lack of keystroke activity and "little put forward by the [employee] that assisted [the] argument that the cyber records were inaccurate".
